WATER-TRAP.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed June 3, 1908. Serial No. 436,401.

T 0 all whom it may concern:

Be it known that I, Fnnnnnjron WV. MEIER, a citizen of the UnitedStates, residing at- Upper Sandusky, in the county of WVyandot and Stateof Ohio, have invented certain new and useful Improvements in lVater-Traps, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to improvements in sewer traps, and the mainobject of my invention, is the production of a trap, adapted to be usedespecially in cellar drains, and which are so constructed as to bereadily and quickly installed, and which will allow all water to flowinto the sewer or drain, but will prevent the escape of sewer gas or thebacking-up water through the trap, from rising waters, into the cellar.

This improved trap, comprising primarily a casing, which is adapted tofit horizontally into the upper end of the drain pipe, and is providedwith a screen at its mouth to prevent large obstacles from entering theeasing, and is further provided with a trun cated-conical member havingan open lower end, over which swingingly, tiltingly and slidably fits asimilarly shaped closed bottom member, which when the water enters thecasing will allow the same to flow into the drain pipe, but which whenthe water begins to back willrise, closing the lower open end of thetruncated conical member, so that no egress of water or gas is allowedbeyond this point. In order to assist in the easy operation of the trap,I mount the same upon a roller, which holds the trap properly centeredand provides an anti-frictional bearing for the trap.

To more clearly illustrate my invention, attention is invited to theaccompanying drawings, in which Figure l is a longitudinal sectionalView through my trap and the upper end of a drain pipe, the trap beingin the position it assumes when allowing water to pass into the drain.Fig. 2 is a similar view with the parts in the position they assume whenpreventing the escape of water and gases. Fig. 3 is a cross section online Ia-00, Fig. 1. Fig. 4 is a cross section 011 line yy, Fig. 1, andFig. 5 is a detail view of the trapping member and its guiding means.

Referring to the drawings :-The numeral 1 designates a horizontal inletend of a drain I or sewer pipe, in which is adapted to fit thehorizontal outer casing 2, of my invention, the flange 3, resting uponthe upper end of the pipe 1 and holding the casing in place therein.This casing 2, has mounted therein the short straight sleeve or pipe 4,which is secured within the casing at its top by means of the device 5,while at its lower edge, I secure it to the casing as at 6. Carried bythis pipe 4 and extending into the casing 2, is the inverted truncatedspout or member 7, whose lower end 8, is open and is adapted to directthe flow into the drain pipe.

Slidingly, swingingly and tiltingly mounted within the casing 2, andbelow the lower end of the spout or member 7 is the trap or cup 9, whichtapers from the closed bottom 10 to the open discharge end 11, the walls12, being tapered on the same incline as the walls of the spout, so thatwhen the trap or cup 9, is seated the entire lower end of the spout isclosed, as shown in Fig. 2. When the trap is allowing water to flow intothe drain it assumes the position shown in Fig. 1, and the water flowsin the direction of the arrows.

In order to properly guide the trap or cup 9, in its movement and assistin its opening or closing the spout, I mount upon the inside of thecasing 2, the rods or runways 18, for the reception of the roller orroller bearing 14, which is journaled in the outer end of the arm orbracket 15, which is carried by the trap or cup 9. One or more of thesemay be employed without departing from the spirit of my invention.

By mounting the cup 9 as shown, it normally assumes the closed position,as shown in Fig. 2.

In order to prevent obstacles from entering the casing 2 and the spout 7I place the screen 16 over the upper end of both.

From the foregoing description taken in connection with the drawings, itis evident that I provide a trap of this character and for this purpose,which when made of a non eorrodible metal such as brass, is durable andby reason of its long life inexpensive; while at the same time by reasonof its simplicity is very practical and useful.

hat I claim, as new is 2 1. In a trap, the combination of a horizontalcasing adapted to be inserted into the end of a drain or sewer pipe, atapering spout mounted therein, and a trap or cup slidingly andswingingly mounted in the casing below the spout, whereby the spout isopened or closed thereby.

2. In a trap, the combination of a horizontal casing adapted to beinserted into the end of a drain or sewer pipe, of a tapering spoutmounted therein, a trap or cup slidingly and swingingly mounted in thecasing to control the exit of the spout, and means for guiding the trapor cup within the casing.

3. In a trap, the combination of a horizontal casing adapted to beinserted into the end of a drain or sewer pipe, of a tapering spoutmounted therein, a trap or cup slidingly and swingingly mounted in thecasing to control the eXit of the spout, and antifrictional means forguiding the trap or cup within the casing.

4:. In a trap, the combination of a horizontal casing adapted to beinserted into the end of a drain or sewer pipe, of a tapering spoutmounted in the casing and having a reduced lower end, and a tapered cupslidingly and swingingly mounted in the casing below the spout the wallsof which are of the same taper as the spout, whereby as the cup swingstoward the spout the entire lower end of the spout is sealed by the cup.

5. In a trap, the combination with the horizontal. inlet of a drainpipe, of a casing adapted to be inserted horizontally in said pipe, atapered spout carried by said casing, and a cup swingingly mountedwithin the casing adapted to normally swing toward and cover the mouthof the spout.

6. In a trap, the combination of a horizontal casing, a tapered spoutmounted therein, a rod mounted within the casing; upon the upper sidebeyond the inner end of the spout, and a tapered cup swingingly 40connected to said rod, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
